If you have had the SL3's since 1997 and have never replaced the panels, a new set of panels will really bring the sparkle back to the speakers. The SL3's are one of my favorite Martin Logans. I think the new panels are around $600-$800 and will really renew them. A pretty inexpensive upgrade and very easy to replace.
